What kind of test did you run?
Are you kidding? The toughest! Robbie on his high-torque Open Class bikes tearing up tracks and parking lots, pulling wheelies, etc.
The cheaper chains (like the discount, low-grade stuff) just wore out and broke quickly (and we're far better than most at keeping them well-lubed). Two brands were so bad we could twist them in knots with our bare hands with very little effort.
The Zocchi/BiZeta 25H and DID 25H chains definitely last the longest and perform the best but I gave the Zocchi/BiZeta the nod because when it came off the sprocket it didn't twist out of shape, the DID, did... lol.
One thing to definitely watch out for is that some brands are too narrow and they end up "gripping" the rear sprocket. The net result is really excessive friction and heat buildup which will freeze/lock up the links (slowing you down) and eventually, quickly snap the chain. We got screwed over really bad with chains like this at the Vegas event. When Robbie came off the track some of the links were glowing red! and the rear wheel was barely able to turn because the chain links were frozen.
